It feels new. X is light, Y is medium, and A is heavy. B changes your fighting style. Each charecter has two.

False, B is the character trait button, it does different things for different characters. It does change fighting styles for characters like Nightwing and Wonder Woman, but for Batman it releases bats around him that can increase your combo, or Lex Luther gives him a sheild that makes him invonerable for one hit.

And to address the fight stick, they have already said that you can use the base layout, but if you'd like you can change the button layoutfrom the menu screen. They also took it a step further and allow you to change the buttons from the pause menu during a fight. In the last MK I believe you had to go to the main menu to do that.

hope this was helpful and didn't come off rude, it was not my intention.
